4. Description of Sensor Functions
Adjust the parameter
The ultrasonic sensor features a switch output with two teachable switching points. These are set by applying the supply voltage - UB or + UB to the TEACH-IN input. The supply voltage must be applied to the TEACH-IN input for at least 1 s. LEDs indicate whether the sensor has recognised the target during the TEACH-IN procedure. Switching point A1 is taught with - UB,A2 with +UB. Eight different output functions can be set.
Switching point, Setting distance only after power on. The internal clock can assure can't be changed after 5 mins when power on. If want to change the switching point, the user can only setting the request distance after power restart.
TEACH-IN window mode, normally-open function

Default setting of switching point
A1=blind range,A2=nominal distance
